Hi there,
I recently converted my new Super D to use Graflok backs, and published a blog about it. Despite the usual approach of chopping up a Graflok and gluing it in place, I think that my approach is less invasive and certainly cheaper. At present I can also confirm that it is faster and easier to load than an actual Graflok, it seems this is the case because of the chamfered sliders.

I am curious to know how he does his conversion, can you send me a picture? Last I communicated with him was to let him know I had received the Pacemaker I bought from him, but he seemed short tempered, having just gone through some surgery. So it had not occurred to me to email him until after I had finished my design, which is not particularly invasive.

I made an adapter plate from 1/4 inch thick birch plywood that fit into the back frame once the original Graflex blocks were removed and fitted a Roll Film Holder so that any make of RFH for the format would fit. I also shimmed the ground glass an equal amount. The camera is a 2x3 RB Series B. The supplied 127mm Ektar would infinity focus at f11~f16, a 135 or longer will infinity focus wide open._________________The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU.
